The two dimensional N=(2,2) Wess-Zumino Model in the Functional Renormalization Group Approach

Understand

We study the supersymmetric N=(2,2) Wess-Zumino model in two dimensions with the functional renormalization group.

• At leading order in the supercovariant derivative expansion we recover the nonrenormalization theorem which states that the superpotential has no running couplings.
• Beyond leading order the renormalization of the bare mass is caused by a momentum dependent wave function renormalization.
• To deal with the partial differential equations we have developed a numerical toolbox called FlowPy.
